I am new to the forum but allready had some great tips and advice thanks.

I need a little more help as I dropped a valve on my 2000 bike a few weeks ago which snapped the con rod and then went through the engine casing, nice mess.

I finally picked up an engine yesterday only issue is that the replacement engine is fitted with "california emmsion system" think thats what it is called. The only issue is

the loom doesnt match up with my current bike. I was thinking of removing the system and fitting the normal stuff from my old engine.

There is also a loom coming from slightly aft of the starter motor probably from the gearbox but not sure what this is.

Any advice would be appreciated.

Those motors came with an air injection module at the exhaust pipe. I did the same thing to my 00 a couple of years ago. Just remove the extra air hoses and splitters from the air pump that's mounted on the back of the motor. Make the new motor look like the old one and block those injection boxes.

I just used my original loom and it wasn't a problem. Just plug everything in where it was pulled from and you're good to go. Unless....

...Unless your new motor isn't from a speed 4 or a TT. If it isn't, you've got some work ahead of you because the cylinder heads are different between those motors and the daytona 4cyls.

Some newer speed 4's had different fuel injection systems on them too 1 hose vs 2.

Thanks I think it must be the Daytona engine as there are no fuel injection port below the air inlets.

A large problem I think. What course of action would anyone recommend?

1. Change the head from the old engine if this is compatible.
2. Get the fuel injection set up for a Daytona if this would work.
3. Try and speak to the bloke who sold me the bike as it was advertised as a tt600 engine and not a Daytona and return it, it did come with a 28 day warranty.
4. Or any other advice.

Take a look at the exhaust ports. I know for sure they are oval on a TT600, but I can't remember if they are round or oval on a Daytona motor. I am pretty sure they are round.

I believe Will is correct about the exhaust ports. Take a look at the right side of the head and locate the single bolt. Is it located towards the top center, near the half moon gaskets, or is it lower down and towards the front?

Ok will look at the enigne next time I visit the bike club probably this evening but think the exhaust ports are the same as my old tt engine.

which leads me to belive it may be a newer speed four engine as the engine looks similar in all asspest with the exception of the fuel injection ports. The fuel injection system mentioned by wagner did this feed straight into the throtle bodies with the airtubes also as there were also no airtube connections on the black throtle body connecting rubbers.

If this is the case if I purchased the throtle bodie for a newer engine and bolt it on would that work.

would there be any modifications for the fuel tank with only 1 delivery pipe?

Would my fuel injection require remapping as it is currently set up for a 2003 tt engine with after market exhaust?

Thanks for all the help it is much appreciated.

I have recently purchased a Speed4 engine (I think) thinking it was the same as my tt600, but as this is a newer model the fuel injection ports are absent from the cylinder head.

I was wondering for these model engines do the fuel injectors fit straight into the throttle bodies along with the air tubes.

Also I have been told in another thread that these are single fuel delivery hose, if this is the case would I be required to modify the fuel tank?

Any assistance on fitting this newer Speed4 engine to my TT600 would be very much appreciated.

I think you have a Daytona engine as i have an 06 speed four and it has the injector holes in the head but the later type fuel pump and rail with only one pipe, not a feed and return. The engine on the speed fours are all black and I think the daytona ones had black side covers with the main block silver but I'm not sure. To convert it to fit to a tt would require a lot of work and extra bits. So unless its a 650 motor I wouldnt think it would be worth it although it has been done before http://www.triumphrat.net/triumph-su...t-finally.html

It sounds like you got a later S4 motor. It's the same except the fuel feed. You would need to change your fuel pump to a newer S4 pump, but nothing else is likely to need altering. I could be wrong, since I haven't attempted any of this, but Triumph didn't put Kiehin injection on any S4s, and never publicized any upgrades to the Sagem injection. The only reason I can think of for changing the fuel delivery design is to make it the same as every other bike in the Triumph line. It would simplify parts sourcing.

That's sorta wierd. I think the FI was the same on all the TT's & 4's with the exception of the fuel rail. But it sounds like you have a you didn't get the whole engine with valve bodies, just the motor.

Look at the coolant lines on the shifter side of the motor. Is it the same as the motor that was in your tt? Also, is the motor black? if the motor is shiny black, it's from a speed 4. The motor should be identical. Can you take some pics and post them up here? It might make the diagnosis easier.
